According to the underground pipeline drawings provided by the owner, make site investigations. At intervals of 30m on each route excavate wells manually to check whether the entire crosssection has other pipelines and its distribution to take effective protection measures. 3） 根據(jù)基礎(chǔ)和土質(zhì)、現(xiàn)場(chǎng)出土等條件要合理確定開挖順序。Gravel type soil first use pick to loose, then forward excavate with each layer depth depended on the thickness of digging soil. Clear the bottom and dig out the earth by layer and then excavate gradually. 5) 在開挖槽邊棄土?xí)r，應(yīng)保證邊坡和直立幫的穩(wěn)定。開挖過程中嚴(yán)禁超挖，以防擾動(dòng)地基。When C581 South Line temporary road through the warehouse of other contractor, dig down and cover with wooden poles until all cable trench is excavated to the final parts.人工開挖路線（A472 至 B301S 支線）Manual excavation line (A472 to B301S Branch)在人工開挖路線上，安排人員進(jìn)行開挖，不得機(jī)械開挖。同時(shí)應(yīng)在坑（槽）外側(cè)圍以土堤或開挖水溝，防止地面水流入。Earth excavation should not be done in the winter period. If necessary, take winter program.采用防止凍結(jié)法開挖土方時(shí)，可在凍結(jié)前用保溫材料覆蓋或?qū)⒈韺油练宜?，其翻耕深度?yīng)根據(jù)當(dāng)?shù)貧夂驐l件確定，一般不小于 0．3m 。The construction sequence is unreasonable: earth excavation should begin from the lower place, layer by layer and section by section in turn。并應(yīng)經(jīng)常測(cè)量和校核其平面位置、水平標(biāo)高和邊坡坡度是否符合設(shè)計(jì)要求。Note subsidence and deformation of neighboring existing buildings or structures, roads, pipelines etc. Take protective measures with design and construction unit and construct observation on settlement or displacement. 3) 在敷設(shè)有地上或地下管線、電纜的地段進(jìn)行土方施工時(shí)，應(yīng)事先取得有關(guān)管理部門的書面同意，施工中應(yīng)采取措施，以防止損壞管線，造成嚴(yán)重事故 Conduct earthwork on the area needs to lay ground or underground pipelines, cables prior to getting written consent of the relevant administrative departments. On construction take measures to prevent damaging pipelines and cause serious accidents.八. 施工記錄 Construction of Record1) 自互檢記錄。Build site roads and appropriate work area. Widen and strengthen order to facilitate safe 9 / 11construction.2） 電纜溝開挖工程應(yīng)注意邊坡和基坑的穩(wěn)定性，一般應(yīng)按先深后淺的順序施工，并應(yīng)采取必要的保護(hù)措施。Lay cables then backfill after excavation without longterm exposure. Clear debris in advance and backfill uniformly on both sides and pact4） 夜間施工時(shí)，應(yīng)合理安排施工項(xiàng)目，防止挖方超挖超深。Around cable trench set protective railings as per safety requirements.7） 不宜在雨季施工，并事先作好地面和地下排水設(shè)施。Do not do the next process when finish the excavation or on raining season, but leave 150～300MM base elevation until the next process.10）開工前準(zhǔn)備好安全設(shè)施，現(xiàn)場(chǎng)安排充足的管理人員，做到隨時(shí)有人巡檢；機(jī)械作業(yè)必須有人守護(hù)，防止事故發(fā)生；進(jìn)場(chǎng)的工人必須進(jìn)行安全教育培訓(xùn)，挖土前必須進(jìn)行技術(shù)交底并簽字，同時(shí)與工人簽定安全用工合同。 sign safety employment contracts with workers.10 / 11附廠區(qū)電纜溝圖： Attached: cable trench drawing11 / 11。 machine operations must be guarded to prevent accidents。施工中應(yīng)防止地面水流入溝內(nèi)，以免邊坡塌方或基土遭到破壞。Rationally arrange night construction projects and prevent the ultra excavation. The construction set up adequate lighting facilities and red light warning on dangerous lines.5） 土方開挖前，應(yīng)會(huì)同有關(guān)單位對(duì)附近以有的建筑物、構(gòu)筑物、道路等管線進(jìn)行檢查和鑒定，并在整個(gè)施工期間，加強(qiáng)監(jiān)測(cè)，發(fā)現(xiàn)問題應(yīng)與設(shè)計(jì)或建設(shè)單位協(xié)商采取防護(hù)措施，并及時(shí)處理。電纜敷設(shè)完畢，應(yīng)抓緊回填工作。Cable engineering subitem quality inspection and evaluation records3） 分項(xiàng)工程驗(yàn)收記錄。Do not collide targeting criteria piles, axis cited pi
